Rotor pump

Rotor pump is also named rotary lobe pump, threelobe pump, sole pump, etc.

When the 2 simultaneous reverse rotating rotors (with 2-4 gears) revolve, it produces suction force at the inlet (vacuum), which intakes the material delivered. The 2 rotors divide the rotor housing into many smaller parts and revolve in the sequence of a→b→c→d. When it revolves to position a, only housing I is filled with medium;when it revolves to position b, housing B encloses part of the medium; when it goes to position chousing A encloses medium, and finally it goes to position d, then housing A, B and II are interlinked and the medium is transported to the outlet. As this process is repeated, medium (material) is transpor-ted continuously.
